I hate to see that you have no replies so far. Either the pundits have already decided that early November is too late to get to the Pacific, or they are still studying.
I am an outsider, from Europe, and suggest that you concentrate on two options:
1. Connect to the Western Express route in Cortez-CO -via Abiquiu, Chama and Durengo- to finish in San Francisco.
2. Follow Route 66 to LA.
My scenic preference, disregarding the season, would be the former.
Regarding the Western Express, Adventure Cycling recommends the route from early summer to mid-fall and the highest point is 8573 ft in California. So this may be too late. Still I recommend to buy the map set which has a lot of specifics about weather conditions and places to stay. It may be an inspiration for coming years.
You are less likely to get stuck on Route 66. I have cycled it this spring. It took me 19 days from LA to Santa Fe, so you might finish it in November. The highest point is the 8000 ft Continental Divide between Grants and Gallup- NM, which you reach earlier and will probably be longer snow-free. With a good daily distance strategy and effort you can find a hotel every night. The advantage regarding services is that you are near to an Interstate. This is also a disadvantage, as you are required to cycle short sections on it (see my journal http://www.crazyguyonabike.com/doc/?o=1&doc_id=12167&v=17N#323680
). For New Mexico, Adventure Cycling has published a provisional itenerary with services : http://usbr66nm.bicyclemaps.org/Route_66/Maps_files/USBR%2066%20NM.pdf
. The hot Mohave Desert may have cooled down by end of November.
